TMA includes several variations according to the attachment probe and the methods of the attachment probe are applied: compression loading, tensile loading, penetration, 3-point bending methods.
Rigaku adopts differential expansion principle where the thermal expansion or shrinkage generated from the detection mechanism itself can be canceled. It offers high accuracy and excellent reproducibility in expansion and shrinkage measurements, even with low expansion materials or thin materials. It can also measure using the non-differential or conventional expansion method.
Dynamic TMA mode that is a temperature control method in which the sample’s shrinkage associated with sintering is measured not by constant heating rate but the heating rate continuously changes depending on the sample’s shrinkage rate. Thru this temperature control, the temperature program simulation can be applied to inhibit grain grows and obtain a sintered material.
